Terminal Blocks - Headers, Plugs and Sockets have a wide range of applications across multiple industries, ranging from automotive to industrial to power electronics. One type of terminal block used in a wide variety of applications is the ELFR19280E. This terminal block is suitable for low signal connections such as in networking and telecom applications. This article will provide an overview of the ELFR19280E’s application field and working principle.

ELFR19280E is an economical and compact female shrouded header. With 1.27mm pitch and 2.54mm grid, it supports two to eight circuits and can be daisy-chained in any combination. The ELFR19280E is made of UL94V-0 flame-resistant material and has UL1059, UL489, IEC60715 and GB14048 certifications. It is commonly used as an input/output port for circuit boards and is especially suitable for low signal connections. This terminal block features 3 to 7.5A of current rating and a voltage rating of 125V or 250V DC.

The ELFR19280E has a wide range of applications, including the following:

• Connecting devices to boards (e.g., sensors, potentiometers, switches, etc.)
• Communications enclosures (e.g., routers, modems, etc.)
• Power electronics (e.g., circuit breakers, isolators, safety switches, etc.)
• Industrial automation (e.g., conveyors, robotic arms, etc.)
• Automotive (e.g. radio receivers, climate control, etc.)

The ELFR19280E has a unique working principle in comparison to other terminal blocks. Rather than having to screw, crimp, or solderm its terminals into place, it utilizes a unique design with lever arms. The lever arms allow for quick and secure connections without the need for additional tools. The lever arms are twisted to the right to unlock them from their clamped position, and the terminal is inserted into the chamber. Once the terminal has been inserted, the lever arms can then be twisted to the left to clamp the terminal in place. This process ensures a secure connection that can withstand high amounts of vibration and current.

In conclusion, the ELFR19280E is an economical and compact female shrouded header suitable for a wide array of applications, ranging from automotive to industrial to power electronics. It features a current rating of 3 to 7.5A and a voltage rating of 125V or 250V AC/DC, making it highly suited for low signal connections. Additionally, its unique lever arm designs makes it even easier to connect, disconnect, and reconnect components without the need for additional tools.
